Application filed February 15, 1912. Serial No. 677,689.

To all whom it may concern:

Beit known that I, GEORGE SMITH Brianne LEE, a citizen of the United States, residing 1 at Chicago, inv the county of Cook and State of Illinois, have invented certain new and useful Improvements in Di'shlVashing Machines, of which the following is a specification, reference being had to the accompany ing drawings.

My inventionrelates to dish-Washing machines, and has for its object to provide certain improvements in machines of the type shown and described in Letters Patent No. 821,696 and 852,866, bothgranted toA. l/V. Bodell, in which one or more paddle-wheels are employed to direct the wash-water against the dishes. I accomplish this object as illustrated in the drawings and as hereinafter described. .Whatl regard as new is set, forth in the olainis. i

In the accompanying 'drawings,-'-Fignre lis a longitudinal vertical section of my improved machine on line -11 ofFig. 6; Fig. 2 is a plan View thereof; Fig. 3 partial side View illustrating the mechanism for re toting the paddle-wheel; Fig. is an on larged detail, shi ring the manner of suph porting the dish-holding basket while the dishes are being washed; Fig. 5 is a vertical CIOSSr-SQClZlOIl on line 5-'5 of Fig. 1, looking to the right; Fig. 6 is a vertical cross-section on line 6-6 of Fig. 1, looking to the left.

As clearly shown in Figs. 1 and 2, my improved disliqvasliing machine comprises a dish-washing tank or compartment 7.ja rins ing tank or compartment 8 at one sideof the washing tank i", and a compartment 9 at the opposite side of the washing tank, in which is placed the paddlc-wheel or equivalent agitating means. The wa'shingtank 7 is separated from the rinsing tank 8 by a partition 10 having an overflow outlet 11 near its upper end-so that water from the rinsing tank may becaused to overflow into the'w-ashing tank.

Both the washing and rinsing'lanks are open at the topiorlhe introduction of the basket contain ng the dishes. The washing ere provided to prevent the basket from striking the paddle-wheel.

tank is notsepa rated from the compartment r which contains the; paddle-wheel, but

guards 12, preferably metal strips or rods,

H p 7 As clearly showman Fig. 1, the bottom 13 of the washinglank is at a considerably lower level than i the bottom of the compartment 9, the [3111* pose ofthis arrangement being to proyide a water.

The axis of the paddle-wheel l is provided with a pinion 1b, as shown in Fig. 3 which meshes with a gear 1'? rotated by a crank 1S, or other suitable means, such as a motor. As best shown. in Fig. 2, the con'ipartnient Q tank 7' so that water cannot splash out on til the floor. 19 indicates a traypwhich extcnds over the "top of the compartment 5) and serves as a convenient place for filling the basket or depositing dishes to be washed.

The object is to provide 'suflicient depth of water at the under side of the paddle-wheel 15 to enablefit. to operate to the best advantage. -The pi e 31 connects with the any other suitable ,heating means may be "employed, such as a gas burner.

. 34 indicates a water supply pipe communicating with the rinsing tank 8.-

' 35 indicates a trolley-track. which extends longitudinally of the machine and is substantially-over the center thereof, as shown inv Figs. 5 and 6, being supported by curved standards 36, as therein shown' The track 35 is for the purpose of supporting a trolby 37 by' which the usual dish-holding basket 38 is suspended and shifted from one osition to another. As shown in Fig. l, the

asket38 is provided with a bail 39 which is" engaged bv a hook 40-at the end of a I chain -41 whichruns over a pended from the trolley 37.

galley 42 susthe'basket may readily be moved into its different positions and be lowered into the washing and rinsing tanks orlifted out of.

such tanks.

In practice the filling basket, resting on' the tray 19," is connected with the chain 41 by means of the hook 40 and is then lifted and moved along until it is over the washing tank 7, when it is lowered into said tank until it rests on the bottom thereof, the

' I dishes being'then submerged in the water in saidtank. At this time the paddle-wheel is not operated. TAfter the dishes have soaked long. enough, the basket is raiseduntil it occupies an .mtermediate position in the washing tank, and the paddle-wheel is driven rapidly, thereby forcing the wash- -wa ter violently against and through the dishes. This is continued until the dishes are thoroughly cleansed.

' By extending the bottom of the washing tank a considerable distance below the bottom of the compartment 9, a settling chamher or compartment is provided in which the solid matter washed from the soiled "dishes is deposited and where it remains practically undisturbed notwithstanding the agitation of the water in the upper portion of the tank, since, while the paddlewheel, 15 is in operation the water supplied to it omes from a zone above the settling chain er and not from the settling chamber itself, the water in which is prevented from flowing under the paddle-wheel by the construction shown, and consequently is not agitatedto any great extent.

, In order to support the basket in its inthis meanschain-"41 p1aced in suitable position so that when said hook engages'such-link the 'basket will be held suspended at the proper height. The engagement of the book 43 with the link 44 is shown-in Fig. 4.

After the dishes have been thoroughly cleansed, the basket is hoisted out of the washing tank and deposited in the rinsing tank, which is full of very hot water, and after being rinsed are withdrawn and the basket is deposited .on the tray 20.

It will be seen that by the construction described I provide a very compact apparatus in which the several operations of washing the dishes may be expeditiously and efliciently carried on. imprdved machine is simple in construction and therefore the cost of manufacture is not only reduced but there is. very little mecha-.

nism to get out of order, and consequently the cost of maintenance is very low.

While, my improved machine is intended primarily for washing dishes, it may beused for any other purpose to which it is adapted, and the claims are therefore to be construed accordingly.

That which I claim'as my invention, and desire 'to secure by Letters Patent, is,-

1. A washing-machine, comprisng a washwater holding-tank, a compartment at one side thereof and communicating laterally therewith, and means in said compartment for throwing wash-water against the articles to be washed, said tank extending below the level of the bottom of the compartment containing said water-throwing means to provide a settling chamber below the washing tone in which solid matter may accumulate.

2. A washing-machine, comprising a washwater holding-tank, a compartment at one side thereof and communicating laterally therewith, means in said compartment for throwing wash-water against the articles to 4 be washed, said tank extending below the level of the bottom of the compartment containlng said water-throwing means to pro- .vide a settling chamber below the washing Moreover, my

zone in which solid matter may accumulate,

and means for supporting the articles to be washed in said tank above said settling chamber.

3. A washing-machine, comprising a wash- -water holding-tank, a compartment at one side therebf and communicating laterally therewith, a paddle-wheel in said compartment and operating by its rotation to discharge water into the upper portion only of said tank, said tank being extended below the zone of operation of said paddlewheel to provide a settling chamber in which solid matter may accumulate.

6. A dish-washing machine, comprising a washing tank open at the top, a compartment at one side of said washing tank and opening thereinto, the bottom of said Washing tank extending below the bottom of said compartment, means in said compartment for throwing the Wash water against the dishes to be washed, and an overflow outlet leading from said washing tank at a point above the bottom of said compartment.

'7. A. dish-Washing-machine, comprising a washing tank open, at the top, a compartment at one side of said washing tank and opening thereinto, the bottom of said Washing tank extending below the bottom of said compartment, means in said compartment for throwing the wash Water against the dishes to be washed, and a tray arranged over said compartment.
